Economic Growth

An increase in the economy's potential level of real output and an outward movement in the economy's production possibility frontier (PPF).

Short run economic growth is a movement from point X, inside the PPF, to Y on PPF1. Short run growth occurs when the economy recovers from a recession and employment increases.

Long run economic growth is shown by a movement from point Y to point Z. The definition mentioned above applies to LONG RUN economic growth.
